Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hanging wire car for an overhead line used during overhead line work of a transmission line.

[Conventional technology]

As a conventional suspension wire car for overhead lines of power lines, a vertical cross section is provided below the hook (a) shown in FIG. Attach the fixed frame (b) that has been bent into a shape, and make it face the fixed frame (b), The upper and lower parts of the open-close frame (C) are joined from the left and right, and the messenger wire (D) is inserted into it, clamped and held by the screw (E), and the fixed frame (B) and the open-close frame (C) It is known that the overhead wire roll (f) can be held between.

[Problems to be solved by the device]

In the suspension wire car for overhead lines of conventional power transmission lines, when changing the mounting location on the messenger wire,
If you loosen the screw (e), the open / close frame (c) side may open and fall off the messenger wire. I had to put the messenger wire back on, and slide it over the messenger wire to change the position.
Therefore, there is a problem that the messenger wire necessary for mounting and changing the position on the messenger wire is not only labor-intensive but also dangerous and extremely troublesome.

The present invention has been made in view of the above problems of the conventional technology. The purpose of the present invention is to attach and move a messenger wire in a comfortable posture, efficiently, and with safety. It is intended to provide a suspension wire car for overhead power lines.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the hanging wire car for overhead lines of a power transmission line according to the present invention comprises a fixed screw which is pivotally attached to the back side of the hook in parallel with the back side of the hook, the upper end side being pivotally attached to the pivot axis, and the lower end side being inserted. A reed is provided with a tilting tightening plate that tilts in the lateral direction, and fixing rods are fixed to the left and right positions on the upper end side of the tilting tightening plate and project in a U-shape from the side surface of the hook toward the tip side. is there.

[Action]

When the fixing screw is tightened, the lower end side of the tilting tightening plate leans toward the hook side, and the base of the fixed rod attached to the upper end side also leans toward the hook side, and the tip side of the fixed rod rises and is inserted into the hook. The messenger wire A can be picked up from the lower side and pressed against the inner surface of the hook to be held and fixed. Contrary to the above, if you loosen the fixing screw, the tip side of the fixing rod will go down and the messenger wire can be released.
You can immediately move the hook while it is suspended on the messenger wire.

〔Example〕

 Examples will be described with reference to the drawings.

The tilt tightening plate 1 is formed of, for example, a substantially rectangular steel plate, and the lower end side is pivotally attached so as to be tiltable toward the tip end side of the hook about a pivot 3 laterally attached to the back surface of the hook 2. The left and right fixing rods 4 and 4 have bases attached to the left and right positions of the upper end of the tilted tightening plate 1 which is pivotally attached, and are bent into a substantially U-shape in a rod shape so that the tip ends hook toward the tip 5 of the hook 2. The fixing screw 6 which protrudes from the both side surfaces of the hook 2 toward the tip side to form a substantially lower semicircle on the lower side of the hook 2 is screwed into the lower half position of the tilt tightening plate 1 from the outside, and the tip portion is fixed. It is screwed into the back surface 7 of the hook 2. The fixed frame 8 is a steel plate and has a substantially vertical section. It is formed in a shape and is fixed to the lower side of the hook 2 downward. The open / close frame 9 is a steel plate and has a substantially vertical section. It is formed in a shape and is provided at a position facing the fixed frame 8. More specifically, the fixed frame 8 and the opening / closing frame 9 are provided at a position where the fixed frame 8 and the upper end are in contact with each other.
And form a substantially upside down U-shape. The overhead wire roll 10 is installed inside the lower ends of the fixed frame 8 and the open / close frame 9. One end of the screw 11 is fixed to the upper end of the fixed frame 8, and a substantially central position of the screw 11 is inserted into an opening / closing groove 12 which is laterally provided in the upper end of the opening / closing frame 9 and tightened with a wing nut 13.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

Since the hook is always supported by being suspended from the messenger wire, it is not necessary to support the suspension wire car for overhead lines with both hands.The fixed rod can be used to operate the messenger wire with just one hand. It can be pressed and fixed, or it can be loosened and moved as it is, so you can expect efficient and safe work in a comfortable posture.
